one guide to rule them all....possible?

I'm thinking of running a Bionicon v2 chain-guide only after having to retire my Superstar components chain-keeper after 2 years of service. It never really was a fit n forget solution so I'm hoping the Bionicon will suffice on my 1 x 9 BFe.

Any thoughts? Am I better served with something else or even a top & bottom guide combined?

Works components alternating profile ring works fine with 9spd, I use one with a Paul chainkeeper up top and a home-made bionicon-a-like underneath, works pretty well but I've not really given it a thorough testing yet...

Can't comment on the superstar guide. Have been using the E13 XCX for a couple of weeks now and it is working great with a clutch mech. I am using it with an ISCG adaptor which makes adjusting chainline a little easier if needed. However, the chainline was perfect without any shims between the backplate and the ISCG adaptor. It is very solid and very well built (as you would expect for the price).
